Jared Loughner browsed through a Safeway and calmly bought a bottle of water, just before he began the mass shooting that killed six people and wounded thirteen, including then-Congresswoman Gabrielle Giffords.

Loughner's actions are on in-store surveillance video the FBI just released.

At the checkout he looks up as if he knows a surveillance camera sees what he does. He says something in sign language. An FBI agent translates the gestures as, "Today is for my love."

About three weeks before, Loughner made an internet post, saying, "I love you government! I love you!" But his other writings show he thinks most people in government are guilty of treason.

In an e-mail, just after midnight on January 8th he says to a woman. "Please don't be afraid of me. I don't like mass murders."

But he became a mass murderer just a few hours later. Evidence photos show Pima County Sheriff's deputies restraining him, after civilians Loughner down, took his gun and held him until law enforcement arrived.

FBI documents show he said very little in his first hours of custody but while agents drove him to Phoenix Federal Court he heard a fragment of radio news saying Gabrielle Giffords was in the hospital. He said, "that's confirmation to me."

Photos include Loughner's weapons: a 9mm Glock handgun, two 30-round magazines, and a knife. They also include a carefully lettered, cryptic note with references to Oswald, who assassinated President John Kennedy and to Loughner himself, saying both, "Loughner is famous for what he failed to do, and Loughner is infamous for what he failed to do."

Investigators uncovered more evidence of how Loughner planned the attack, including an envelope with Loughner's signature and a note saying, "are the first 2 shells out of my gun" and "I planned ahead and my assassination-Jared Loughner- Giffords."

Other pictures show evidence collected from the scene, objects that had been damaged by bullets and photos of all cars in the Safeway parking lot.

The written documents include a number of tips the FBI received from people who thought they knew or saw a second suspect. That second suspect turned out to be Loughner's cab driver, who was cleared.

Jared Loughner is serving a sentence that will keep him locked up for life: seven consecutive life terms, followed by an additional 140 years.
